METAL-WORKING MACHINE.

Patented Mar. 25, 1919.

Original application led April 28, 1914, Serial No. 834,895. (Patent No. 1,241,254, dated September 25, 1917.) Divided and this application led .Tuly 11, 1917. Serial No. 179,887.

To all whom t may concern:

Be it known that we, THEODORE P. PAYNE, a resident of New York, N. Y., and EDWARD V. lVUirrs, a resident of Newark, New Jersey, both citizens of the United States, have made new and useful Improvements in Metal- Working Machines, of which the following is a specification.

The invention relates to metal punching machines, and more particularly to means for spacing a plurality of punches and their die blocks relatively to each other, and to means for so relatively spacing the respective punches and die blocks by a controlling device operating thereon automatically.

This application is a division of application Ser. No. 834,895, filed by us April 28, 1914, now Patent No. 1,241,254, issued Sept. 25, i917.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and forming a part hereof, illustrate one embodiment of the invention and together with the description serve to explain the principles thereof.

Of the drawings:

Figure 1 is a fragmentary elevation of a machine constructed in accordance with the principles of the invention;

Fig. 2 is a fragmentary, central section, on an enlarged scale, of the punch and die mechanism shown in Fig. 1;

Fig. 3-is a fragmentary plan, on an enlarged scale, with parts in section, of the controlling device of the spacing mechanism; and

Fig. 4 is asection, taken on line G-H of Fig. 3.

Referring to the accompanying drawings,

. illustrating by way of example one embodiment of the invention, means are provided for automatically Veffecting and controlling the relative positioning or spacing apart of the punches, and therewith the corresponding dies, and more particularly for effecting and controlling such relative vpositioning from the distance record sheet. As embodied, one punch and die, or one set of the punches and dies are fixed in position. as shown at the left in Fig. 2. Rotatably mounted in fthe stationary punch block 150 is a shaft 151. Shaft 151 passes through an aperture in the movable punch block 153 and is screwthreaded at 152 to engage an internal thread formed in the aperture in punch block 153. Shaft 151 connects by a universal joint 154 with a short shaft 155, said shaft 155 being journaled in a bracket 156 supported on cross frame 20.

In Fig. 1 is shown the shape a: which is traveled longitudinally by rolls 1 and is stopped and positioned by the head 2, rack 3 and coperating parts, and the punch block 153 and its die block 159 are automatically moved transversely across the work under control of the distance record device to effect relative movement between the punches to space the holes the desired predetermined distance apart across the work.

A similar arrangement is provided for .the-die blocks, a shaft 157 being rotatably mounted in a fixed die block 158.V Shaft 157 passes through a movable die block 159, the shaft having a screw thread 160 engaging an internal thread in the aperture of the die block 159. Means are provided for rotating shafts 155 and 157 to and fro to correspondingly move the punch and die blocks 153 and 159, and as embodied shaft 157 has a beveled pinion 161, meshing with a bevel gear 162. Gear 162 is fixed on a sleeve 163 embracing rod 22. Fixed also to sleeve 163 is a bevel gear 164 meshing with a bevel pinion 165 Xed on shaft 155. Thus shafts 155 and 157 rotate ink unison, while provision has been made by joint 154 for the reciprocation of the punches. Joint 154 also has a telescoping action due to changes in the level of shafts 151 and 155. Sleeve 163 is rotated to and fro by suitable means, such as a bevel pinion 169 meshing with gear 164 and fixed to a shaft 170, to which shaft is also fixed a slip or friction gear 166, driven by a pinion driven by a motor 168.

The movement and position of the punches and dies are controlled by suitable devices, and in accordance with one feature of the invention, this is eected from the distance record sheet or by manually settable devices. As embodied, solenoid operated means are provided for this purpose. On bracket 156 are supported a series of solenoids 171, which have suitable circuit connections to the dissaid spacing.

.rying said y p and decreasing the distance between the 'ord device.

4.l Apunching machine including 1n com-y bination a Iplurality of punches, a head car-` tance record sheet ork to the manually settable devices. The solenoid cores operate pins 172 working in apertures in the walls of the supporting ring or bracket 156. EX- tending downwardly from the bevel gear is a lug 173 which is engaged by any set -pin 172, thus stopping the gear 164, the sleeve 163 and gear 162, and thus positioning the punches and Adies at the desired point. In Fig.l 3 the solenoids .171 are shown in circuit with contacts 174 Vand 175, which cooperate with a distance record sheet X, to control the solenoids as .described to govern the spacing of thepunches and dies.
